This application claims the benefit of the provisional patent application No. 61/801,767, filed Mar. 15, 2013

FIELD OF THE INVENTION

The present invention relates to educational toys and particularly to a manipulative aid for teaching arithmetic concepts. More particular, the present invention relates to teaching arithmetic through repetitive play using vertically stackable, toy building blocks, in the shape of numbers that are scaled according to their height value.

BACKGROUND OF THE INVENTION

Many previous inventions, whether teaching numerical values through elongated blocks or scaling numbers in relation to their value, require users to do the work of associating measurements to their respective symbols (usually painted on the front), or they simply lack the interconnectivity to provide long lasting engagement.

U.S. Pat. No. 3,934,357 to Couvillion and titled: TEACHING METHOD AND APPARATUS, teaches arithmetic using numeric cutouts that scale in height according to their numeric value. While this design succeeds in making numeric values more clear through size representations, the cutouts do not stack one atop the other so that each number is discernable.

U.S. Pat. No. 4,382,794 to Preus and titled: INSTRUCTIONAL AID, is intended to teach basic arithmetic using blocks in the shape of numeric symbols, that have a width value proportional to each number represented; e.g., the “2 block” is twice the width of the “1 block.” While this design is capable of continuously stacking numeric figures on top of one another, because the value representative of the numeral is located on a separate visual plane than the symbol, it is difficult to make the intended key memory associations, or see and apprehend those associations when multiple numbers are stacked on top of one another, as the topmost numeric symbols obscure the other symbols. Both Couvillion and Preus offer limited configurations and limited aggregate morphology.

Other patents such as U.S. Pat. No. 4,430,825 and U.S. Pat. No. 3,918,178 describe inventions that contain the numeric symbols in toy form, but fail to show both critical relationships between numeric symbols and provide a toy that has lasting replay value.

It would be desirable to provide a heavily kinesthetic dependent means for learning number relationships in the form of a stacking numbers toy.

It would be especially desirable to provide educational number blocks whereby the various base-ten numerals may be vertically stacked while maintaining the visibility of the represented number so that comparisons of values may be made by a student while at play.

OBJECTS AND ADVANTAGES OF THE INVENTION

In learning skills that require a lengthy duration to master, kinesthetic learning is only as powerful as the frequency with which it is used. The present invention not only allows the number blocks to be stacked vertically so that students can work with larger math problems, but the blocks stack from many different angles to provide kids with an engaging toy that they will manipulate and enjoy for hours on end. By being visually engaging and functionally instructive, the present invention provides a means for learning numbers and basic concepts core to mathematics wherein blocks representing numbers and their relative values are used for stacking and building. Elements of the present invention encourage students to vertically stack and build a great variety of toy architectural structures. Through the repetition of stacking each number block, students learn to associate each represented number and its relative value in relation to the other number blocks. These associations intuitively reinforce understanding of the base-ten concept and other essential number combinations during play. Block height directly corresponds to respective number value, making critical number associations easily apparent when viewing the numbers. Not only do these aided associations help accelerate the learning of basic number sense, but the stackable design allows users to engage in learning math concepts that span into the more complex realm of fractions, division, percentages. In addition to accelerating the users learning of number sense and basic mathematics, the blocks serve as a powerful visual aid in all forms of arithmetic. Coupled with the design are a series of symbols, including addition, subtraction, multiplication, division, percentages, greater-than, less-than, not-equals, and decimal points all designed in a style unique to this invention. Through repetition and creative exploration the present invention engages students for a time duration necessary to learn basic number relationships, the base-ten concept, and is an engaging visual instruction tool for parent and teacher alike.

SUMMARY

The present invention utilizes the basic numbers zero through ten. A building block is created for each number. With the exception of a zero block having a purely aesthetic shape and size that is nonrepresentational of its value, the number blocks are constructed with specific heights that are relative to one another. The base unit length is derived from the number 1 block which is most often stacked on its side. Accordingly, the base unit length is taken from the width of the number 1 block rather than its height. Each building block has a height in the foregoing base units corresponding to the respective number it represents; e.g., (2=2 units high (height of two “1s”), 3=3 units high). With the exception of the number 1 block, each block is designed to represent its respective number when stacked vertically allowing the person stacking the blocks to associate the respective numeric symbol with its height value. In this way, learning the base-ten concept, key number combinations, and even basic addition and subtraction become intuitive by merely building with the blocks. All blocks stack right-side-up and vertically with all other blocks. Due to the number 4 block's lower right leg, all blocks are four units wide, allowing the number 4 block to be stacked on its side and still remain uniform in width with the other blocks. All blocks have a thickness of two units, allowing users to build within a unified set of measurements.

In one aspect, the present invention includes number blocks that are shaped and sized to stack as building blocks, in multiple configurations.

In another aspect, the width and depth of all number blocks are part of a unified measurement system. For example, the number 4 block can be stacked on its side or right-side up to achieve a represented value and stacks in an interconnecting fashion with the number 6 block to reinforce base-ten combinations. In another example, the number 1 block stacks perfectly with number 4 block to allow it to stand on its lower right leg, aiding the vertical stacking theme. In yet another example, the number 9 block stacks atop the number 1 block to complete a base-ten combination.

The foregoing and other objects, features, and advantages of the invention will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures wherein the scale depicted is approximate.

FIG. 12, which corresponds to the number 6 block, has a height 21 of six base units, a thickness 10 of two base units, and a general width 11 of four base units. The upper right corner of the number element shown in FIG. 12, has a subtracted area 20 of one base unit that allows it to interconnect with the number 4 block (FIG. 10) and maintain a uniform width between the two figures.

FIG. 13, which corresponds to the number 7 block, it has a height 22 of 7 base units, a thickness of 2 base units, and a general width 11 of 4 base units.

FIG. 14, corresponding to the number 8 block, it has a height 23 of 8 base units, a thickness 10 of two units, and a width 11 of four units.

FIG. 15, corresponding to the number 9 block, it has a height 24 of nine units, a thickness 10 of two units, and a width 11 of four units.

FIG. 16 corresponds to the number ten, has a height 35 of ten base units, a thickness 10 of two base units and a width 11 of four base units.

The bottom left corner of the element depicted in FIG. 15 has a subtracted area 20 of one unit that allows it to interconnect with the number 4 block and maintain a uniform width between the two figures.

FIGS. 17 and 18 correspond to the vertical slash in a not-equals symbol, and possess a diagonal length 25 of four and four fifths units, a thickness 10 of two units, and a width 12 of one unit. FIG. 19 corresponds to the symbols greater-than or less-than, and possesses a height 27 of four units, a thickness 10 of two units and a horizontal width 11 of four units. FIG. 20 (orthographic-back view) and FIG. 21 (orthographic-front view), correspond to the mathematical symbols, add, multiply, divide and percent, and possess a height and width 28 of four base units when measured along the cross sections. Width 29 and 31 of each cross section measures one base unit. The thickness of the vertical cross section is split midway through the element depicted in FIGS. 20 and 21 where circular attachments one unit thick connect and produce the division symbol. These circular attachments depicted in FIG. 22, have a diameter 33 of four fifths of a base unit and a thickness of one base unit.

FIG. 24 depicts a grouping of the number 4 and number 6 blocks, and illustrates how the number 4 block can be placed horizontally and stacked with the number 6 block to achieve the same height as when the number 4 block is stacked vertically and interconnectedly, on top of the number 6 block as shown in FIG. 25. Both FIG. 24 and FIG. 25 show how the objects represented can be combined in their respective numeral pairs to match the height of the object representing the integer ten as shown in FIG. 26.
